18QHTF21-2.440-OE

Oscillators Overview

The 18QHTF21-2.440-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 2.44 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features an Enable/Disable control function for power management. It is housed in a compact 4-SMD, No Lead package suitable for surface mount applications. The component supports an operating temperature range of -40°C to 85°C and maintains a frequency stability of ±50ppm.

Oscillators Feature Summary

• Supports active enable/disable control for efficient power management
• Provides LVCMOS output signal compatibility
• Designed for surface mount integration via 4-SMD no lead package

Oscillators Applications

• General purpose clock generation in embedded systems
• Timing reference for low-frequency digital circuits
• Power-sensitive portable electronic devices

Oscillators Procurement Notes

Verify the specific suffix OE indicates the Enable/Disable functionality rather than other variants like PD. Confirm the 1.8V supply requirement matches the target circuit design. Ensure the 4-SMD footprint aligns with the PCB layout specifications. Check that the ±50ppm stability meets the system timing requirements.

Oscillators Selection Notes

Select this component when a low-frequency 2.44 MHz clock is required with power control capabilities. The LVCMOS output ensures compatibility with standard digital logic families. Consider the thermal range and stability metrics against environmental conditions. Compare package dimensions against available board space constraints.

Oscillators Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz timing solutions. The series includes various frequencies and control options such as enable/disable or standby modes. Mercury Electronics is a established supplier of frequency control products including crystals and oscillators.

Oscillators Replacement Considerations

Direct substitutes include the 18QHTF21-2.440-PD if standby mode is acceptable instead of enable/disable. Other frequencies in the same package may serve similar roles if the clock rate differs.
